elf-care barriers to particular behaviour change techniques to be used in practice.
The application of the capability, opportunity and motivation behaviour model facilitated identifying important factors influencing adherence to heart failure self-care recommendations. The model served as a comprehensive guide for the selection and design of interventions for improving heart failure self-care adherence. The capability, opportunity and motivation behaviour model enabled the connection of heart failure self-care barriers to particular behaviour change techniques to be used in practice.Proton beam therapy offers radiophysical properties that are appealing for noninvasive arrhythmia elimination. This study was conducted to use scanned proton beams for ablation of cardiac tissue, investigate electrophysiological outcomes, and characterize the process of lesion formation in a porcine model using particle therapy.
Twenty-five animals received scanned proton beam irradiation. ECG-gated computed tomography scans were acquired at end-expiration breath hold. Structures (atrioventricular junction or left ventricular myocardium) and organs at risk were contoured. Doses of 30, 40, and 55 Gy were delivered during expiration to the atrioventricular junction (n=5) and left ventricular myocardium (n=20) of intact animals.
In this study, procedural success was tracked by pacemaker interrogation in the atrioventricular junction group, time-course magnetic resonance imaging in the left ventricular group, and correlation of lesion outcomes displayed in gross and microscopic pathology. Protein extraction (active caspase-3) was performed to investigate tissue apoptosis. Doses of 40 and 55 Gy caused slowing and interruption of cardiac impulse propagation at the atrioventricular junction. In 40 left ventricular irradiated targets, all lesions were identified on magnetic resonance after 12 weeks, being consistent with outcomes from gross pathology. In the majority of cases, lesion size plateaued between 12 and 16 weeks. Active caspase-3 was seen in lesions 12 and 16 weeks after irradiation but not after 20 weeks.
Scanned proton beams can be used as a tool for catheter-free ablation, and time-course of tissue apoptosis was consistent with lesion maturation.

We sought to determine the relationship between obesity and tumor characteristics in breast cancer patients.
Medical records of invasive breast cancer patients undergoing mastectomy at our institution between January 2010 and April 2018 were reviewed. Patients who had received neoadjuvant therapy were excluded. Patients were separated into obese (body mass index [BMI] ? 30 kg/m) and nonobese (BMI &lt; 30 kg/m) categories and compared using nonparametric statistical analyses.
Of the 415 patients in this cohort, 124 (29.9%) were obese. #link# Obese patients were more likely to present with larger tumors (tumor size ? 2 cm 53.2% vs 41.0%, = .024) and more node-positive disease (46.8% vs 28.9%, = .001). Controlling for confounders, obesity was independently associated with node-positive disease (odds ratio [OR] = 2.00; 95% CI 1.24-3.21, = .004), but not with tumor size ? 2 cm (OR = 1.38; 95% CI 0.87-2.21, = .174).
Obesity is associated with node-positive disease at presentation independent of other factors.

Our aim was to describe changes over time in mental and physical health outcomes, as well as patterns of service utilisation that may have influenced outcomes, in a representative prevalence sample of 641 Western Australians with a psychotic illness who, at Wave 1, were part of the National Survey of High Impact Psychosis.
In Wave 1 (2010, 2012), a two-phase design was employed to ensure representativeness Phase 1 psychosis screening took place in public mental health and non-government organisation services, while, in Phase 2, a randomised sample was interviewed. In Wave 2, 380/641 (59%) of participants were re-interviewed, with interviews staggered between 2013 and 2016 (follow-up time 2.3-5.6 years). Data collection covered mental and physical health, functioning, cognition, social circumstances and service utilisation. Mental health outcomes were categorised as syrvice utilisation appear to have influenced the patterns found.
Although we observed some positive outcomes over time, the sharp decline in access to evidence-based interventions such as community rehabilitation, psychosocial interventions and case management is of great concern and augurs poorly for recovery-oriented practice. Changes in service utilisation appear to have influenced the patterns found.Atrial fibrillation (AF) can be maintained by localized intramural reentrant drivers. However, AF driver detection by clinical surface-only multielectrode mapping (MEM) has relied on subjective interpretation of activation maps. We hypothesized that application of machine learning to electrogram frequency spectra may accurately automate driver detection by MEM and add some objectivity to the interpretation of MEM findings.
Temporally and spatially stable single AF drivers were mapped simultaneously in explanted human atria (n=11) by subsurface near-infrared optical mapping (NIOM; 0.3 mmresolution) and 64-electrode MEM (higher density or lower density with 3 and 9 mmresolution, respectively). Unipolar MEM and NIOM recordings were processed by Fourier transform analysis into 28 407 total Fourier spectra. Thirty-five features for machine learning were extracted from each Fourier spectrum.
Targeted driver ablation and NIOM activation maps efficiently defined the center and periphery of AF driver preferential tracks and provided validated annotations for driver versus nondriver electrodes in MEM arrays.
